AMENDMENT 1
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

8.14.1.101 Safety instructions for table saws
Replace the existing text of NOTE 1 of 8.14.1.101 1) b) with the following new text:
NOTE 1 If an anti-kickback device is not provided, the warning is revised as follows:
Always use saw blade guard and riving knife for every through-cutting operation. For through-cutting
operations where the saw blade cuts completely through the thickness of the workpiece, the guard and other safety
devices help reduce the risk of injury.
Replace the existing text of 8.14.1.101 1) c) with the following new text:
c) After completing a non-through cut such as rabbeting, resawing, or dadoing, restore
the riving knife to the extended-up position. With the riving knife in the extended-up
position, reattach the blade guard and the anti-kickback device. The guard, riving
knife, and anti-kickback device help to reduce the risk of injury.
Replace the existing text of NOTE 3 of 8.14.1.101 1) c) with the following new text:
NOTE 3 If an anti-kickback device is not provided, the warning is revised as follows:
After completing a non-through cut such as rabbeting, resawing, or dadoing, restore the riving knife to the
extended-up position. With the riving knife in the extended-up position, reattach the blade guard. The
guard and riving knife help to reduce the risk of injury.
Replace the existing text of NOTE 1 of 8.14.1.101 1) f) with the following new text:
NOTE 1 If an anti-kickback device is not provided, the warning is revised as follows:
For the riving knife to work, it must be engaged in the workpiece. The riving knife is ineffective when cutting
workpieces that are too short to be engaged with the riving knife. Under these conditions, a kickback cannot be
prevented by the riving knife.
Replace the existing text of 8.14.1.101 2) d) with the following new text:
d) When ripping, always keep the workpiece in full contact with the fence and always
apply the workpiece feeding force between the fence and the saw blade. Use a push
stick when the distance between the fence and the saw blade is less than 150 mm,
and use a push block when this distance is less than 50 mm. “Work helping” devices
will keep your hand at a safe distance from the saw blade.
Replace the existing text of 8.14.1.101 2) f) with the following new text:
f) Never use a damaged or cut push stick. A damaged or cut push stick may break
causing your hand to slip into the saw blade.

© IEC 2021
Replace the existing text of 8.14.1.101 2) j) with the following new text:
j) Feed the workpiece at an even pace. Do not bend, twist or shift the workpiece from
side to side. If jamming occurs, turn the tool off immediately, unplug the tool, then
clear the jam. Jamming the saw blade by the workpiece can cause kickback or stall the
motor.
18 Abnormal operation

– 8 – IEC 62841-3-1:2014/AMD1:2021
© IEC 2021
General test conditions:
a) For these tests, a steel test disc with a thickness of (2,0 ± 0,2) mm and a diameter D is
+20
installed. The steel disc shall have an unbalance of (0,005 × D ) g mm, where D is
expressed in mm. The unbalance may be achieved by either adding or removing material
from the steel disc. The steel test disc adjustments are made in accordance with 8.14.2 a).
The steel test disc is set to approximately one half of the maximum cutting capacity at
the given bevel angle settings. Once the steel test disc adjustments are made, they shall
not be readjusted during the test or prior to the measurements. The steel test disc is
marked as needed with reference points prior to performing the required measurements in
order to ensure consistency of the measurements. The steel test disc is provided with an
attachment point which may be a hole or other means located at a radial distance of
(20 ± 1) mm from the outer periphery of the steel test disc for applying the test forces. The
attachment point may be achieved by the same means as used for fulfilling the required
unbalance.
b) For a table saw with sliding function, prior to the test, lock the saw blade assembly in
the rip cutting position in accordance with 8.14.2 b) and mark the saw blade assembly
position in such way as to detect a displacement from the locked position greater than
1 mm.
c) For each test, the force is applied at the steel test disc attachment point in a direction
perpendicular to the plane of the table top for 1 min. The force is then released and the
amount of displacement of the steel test disc is measured at the same location.
Bevel setting evaluation:
1) The steel test disc bevel angle is set to the midpoint of the bevel adjusting range in
accordance with 8.14.2 a). The steel test disc attachment point is rotated to the 12 o’clock
position. The bevel angle of the steel test disc is measured in the plane perpendicular to
the table top. The accuracy of angular measurements shall be within ± 0,1°. The
measured bevel angle is recorded.
2) The tool is then operated at no-load for 5 min.
3) The steel test disc attachment point is returned to the 12 o’clock position. The test is then
conducted in accordance with c), using a force of 1,1 D.
4) After the conclusion of the test, the bevel angle of the steel test disc shall be measured
as above. The difference between the before and after test measurements of the steel test
disc bevel angle shall not exceed 1°. In addition, for table saws with sliding function,
the position of the steel test disc assembly shall not have displaced by more than 1 mm.
Depth of cut evaluation:
1) The steel test disc is set to 0° bevel angle in accordance with 8.14.2 a). The steel test
disc attachment point is positioned at the 12 o’clock position. The maximum height of the
outer periphery of the steel test disc over the table top shall be measured and recorded.
The accuracy of the measurements shall be within ± 0,1 mm.
2) The tool is then operated at no-load for 5 min.
3) The steel test disc attachment point is returned to the 12 o’clock position. The test is then
conducted in accordance with c), using a force of 1,1 D.
4) After the conclusion of the test, the maximum height of the outer periphery of the steel test
disc over the table top is measured as above. The difference between the before and
after test measurements of the steel test disc height shall not exceed 1 % of D. In addition,
for table saws with sliding function, the position of the steel test disc assembly shall not
have displaced by more than 1 mm.
Saw blade alignment evaluation:
The measurement of 21.103.1 is repeated after the conclusion of the above tests, except for
the initial saw blade set-up alignment.
